PSO2 Music!

[Negadrake]

Been listening to the OSTs of the previous games in the franchise and I've noticed that some of the melodies from a few of the tracks are recycled. I was wondering if anyone could make a list of what songs from older games appear in the PSO2 BGM.
For example, a bit of Cry, for "IDOLA" the holy, around the 2:00 mark forms the main tune for the Dark Falz Arms BGM.
IIRC, there's a bit of Snowstorm / Snowflake from PSZ in the Tundra BGM.

Dragon's Sanctuary has a piece of Aire Iglesia from PSP2i in it.

PSO2 Forest has a piece from PSO1 forest, and skyland has a piece from seabed, but this one is extremely rare to happen (I've only heard that bit 2 times so far, and I've been around since the beginning). The 2 times that bit happened, right after an emergency code I switched from area 1 to area 2, and as the music transitioned to calm, the bit from seabed played. ^^;

Heck, the PSO2 main theme is a remix of the PSO1 theme, Can Still See the Light.
